In a previous number of the Veterinary Magazine, I have given an account of the discovery of Distoma westermanni in the lungs of a cat at Ann Arbor. The importance of the discovery within our country of this dangerous parasite. so common in the East, was emphasized, and an appeal was made for more information as to the presence of lung distomes in various hosts in the United States since, as stated (p. 357), “there is no need of emphasizing the importance of obtaining accurate knowledge as to the extent of the infection among animals, and even man;” . . . though “it is clear that this single case can not be accepted as proof of the establishment of the parasite in this country.”

Last September I received, through the kindness of the author, a paper' by Professor D. S. Kellicott, of Ohio State University, in which (p. 2) is an account of "Distoma sp. in the lungs of the dog." This account recalled Distoma westermanni so strongly that I at once wrote Professor Kellicott asking the loan of some specimens for examination. He had previously written me on the subject, but the letter was forwarded to several addresses and did not reach me until his second came, which was accompanied by a well-preserved specimen in alcohol and a mounted slide of another individual. For his kindness in this respect I am deeply indebted to him. The careful examination of the two, and of the account given by Kellicott, leaves no doubt as to the identity of the form he found with Distoma westermanni.
